TL;DR: Spectroscopic metallicities of the host stars of 226 small exoplanet candidates discovered by NASA's Kepler mission are reported, finding that planets with radii less than four Earth radii form around host stars with a wide range of metallicities (but on average a metallicity close to that of the Sun), whereas large planets preferentially form around stars with higher metallicities.

TL;DR: In this paper, the authors reported 25,563 radial velocity measurements for 1359 single-lined stars in the Carney-Latham sample of 1464 stars selected for high proper motion.

TL;DR: In this article, a spectroscopic determination of the atmospheric parameters and chemical abundance of the parent star of the recently discovered transiting planet TrES-2 is reported, which can be used to directly measurabele from the light curves of transiting planets with much greater precision.

TL;DR: A spectroscopic orbit with period P=3.52433+/-0.00027 days for the planetary companion that transits the solar-type star HD 209458 is reported, based on a new analysis of the iron lines in the HIRES template spectrum and also on the absolute magnitude, effective temperature, and color of the star.
